OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
306 AM CDT Mon Jun 1 2026

FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.

Waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.SYNOPSIS...

High pressure around 30.4 inches over the Great Lakes Region will
continue to dominate the pattern through the middle of the week.
Expect northeasterly winds today to turn more easterly tonight
into Tuesday as the high pressure slides southward. Will see
southerly winds return to Lake Michigan by Wednesday as the high
pressure moves southeast of the Great Lakes and begins to break
down. Winds are expected to gradually increase and shift more
southwesterly for the end of the week as low pressure around 29.7
inches tracks from the Canadian Plains across Ontario through
Thursday and Friday. Accompanying the late week system will be
chances of showers and storms into the weekend.
